Preamble Character(s)

Serial Cmd: <K141,preamble status,preamble character(s)>

Default: ^M corresponds to: carriage return/null/null/null.

Options: Up to four user-defined ASCII characters, including control characters.

Within a Serial Command

To enter control characters within a serial command, hold down the

control key while typing the desired character.

Example: <K141,1,CNTL-m> to enter ^M

Within an Embedded Menu

Control characters entered on the command line are displayed in the

menu as mnemonic characters, such as: <CR><NUL><NUL><NUL>.

To enter a control character from within an embedded menu, first type

in a space (with the space key). This has the effect of allowing the con-

trol key to be recognized as a part of the control character. Next hold

down the control key while typing the desired character.

Example: Space CNTL-m to enter ^M.
